[NeoX Engine] Cyber Hunter .gis animation data

[vchakchina]

Hi. I have unpacked assets from the game Cyber Hunter, which closed in July 2024. I'm actually very interested in the animations from this game.
After a bit of research into all the archive directories, I'm pretty sure that the .gis files are animation files (the folder that stores all the animations has the Chinese name "dongzuoku_gis" - which translates to "Action library").
Also, all the files have the correct name (lobby_emotion_laugh.gis) and are quite large size (typically for game animations lasting ~15 seconds).
After checking the file in Hex, I was able to determine that the first bytes contain a list of bones, followed by, I believe, animation keys.
Does anyone have any idea how to check this file and figure out a way to convert it to more common formats that support armatures with animation (if the file contains rig data) or, for example, how to import animation keys onto an existing armature for which this animation is intended?
Thanks in advance if anyone can help me learn a little more!
